One of my neighbors here in Juneau grows them on the side of his house and has a whole wall of huge hop plants. I don't have a clue how he does it though since we average 230 days of rain and don't get a lot of sun...

I've read about some people in Fairbanks who've been successful though. They grow them near the entry way deck in fron of their house and have some grow lights and heat lamps at the end of the summer when the weather starts to drift.
